6 Claims.

My invention relates to reference systems for materials required in theproduction of commodities, and more particularly to ingredients forbaking doughs, and my main object is to provide a system whichsimplifies and expedites the task of procuring the proper materials forthe particular need.

A further object of the invention is to provide a reference system whichenables the required materials to be determined by accurate means andwithout difficulty.

Another object of the invention is to provide a reference system whichcombines versatility and order of importance in respect to the itemsfiled therein.

A still further object of the invention is to include novel means forconcealing data infrequently referred to, whereby to eliminate itsconsideration during the regular routine.

An important object of the invention is to have the novel apparatusserve as a complete and readily accessible file for the system.

With the aboveobjects in view, and any others which may suggestthemselves from the description to follow, a better understanding of theinvention may be had by reference to the accompanying drawings in which-Fig; 1 is a perspective view of the novel apparatus, open and partlybroken away to reveal a portion of its interior, and also depicting areproduction of a detail;

In the baking industry, various formulas are employed for reference whenpreparing sponge doughs, straight doughs or other mixtures. One systemof reference may employ a large frame or cabinet bearing the entirearray of formulas without distinction as to importance or frequency ofuse. It is apparent that a reference system of this type createsfrequentopportunitiesfor confusion and error in such items asingredients and their weights, resulting in spoiled mixes andnon-uniform or unsalable products. Another method of filing formulas isby impaling them on the desk spindle or hook, or tying them togetherwith a string and suspending them from a hook. Obviously, much time maybe lost in an attempt to find the proper formula in this type ofreceptacle, not to speak of chances to make errors and the inevitablesoiling or tearing of the sheets so that they are unfit for use. A stillfurther method involves daily repetition in copying identical kinds andamounts of ingredients for individual doughs and is costly because muchtime is devoted not only to necessary reference items but to many whichare infrequently needed, not to speak of confusion and probability oferrors incident to work of this kind. It has therefore been my intentionto eliminate the above difficulties by the provision of a system whichminimizes complications, hazards and efforts incident to filing andselection of formulas in the baking industry or in fields dealing withcorresponding conditions.

In contemplating a unit for a formula file, a cylinder or roll bearingthe formula in relation to a master card appears to be the mosteflicient expedient. Thus, with values stepped off along the peripheryof the cylinder, the rotary adjustment of the latter in relation to themaster card will present the successive values in positions adjacent tothe card and so facilitate the reading or selection of such values.

In accordance with the expedient just outlined, specific reference tothe drawings indicates an apparatus equipped with a set of the rollunits mentioned. Thus, a rectangular housing or cabinet is illustratedin Figure 1, such cabinet having suitable means ID to suspend it on awall, and being formed with a top H, a bottom l2, a medial shelf I3,ends l4, and a door l5 hinged to the cabinet at one side, as indicatedat l5e. The door and I9.

As seen in Figures 1 and 2, the space between the door l5 and thepartition 16 is largely occupied'by upper and lower sets of the verticalcylinders or rolls 20 around which are wrapped the formula sheets 2 I.

One of these is shown-in the center part of Figure 3in the fiat formpreliminary to being wrapped, and it is seen that the sheet is made withinward terminal bends 2Ia which tuck into a longitudinal slot 26a cut inthe periphery of the roll when the sheet is wrapped, as clearlyindicated in the right hand portion of Figure 3. In order to retain thesheet in the wrapped form, I employ a wavy strip 22 of spring steel, thestrip having a horizontal top bend 22a. 'Ihe'strip is inserted edgewiseinto the space between the sheet bends ZIa, as suggested by the arrow inFigure 3, so that the stripappears lodged as in the upper center ofFigure.

1, with its top bend 22a overlying the top of the roll sidewise of thegroove 20a. On account of its wavy form, the strip 22 is put undertension when lodged between the bends Zla, and therefore bears againstthe latter to retain them in place.

In order that the set of rolls be properly mounted in the cabinet, theshelf I3 is made with apertures I3a at selected points to receive'centerpins 2327 depending from the lower ends of the rolls and indicated bydotted lines in the center of Fig. 4. The upper end of each roll isformed with a pair of diametrically spaced cavities 200 intowhich dependpins 231 carried by a horizontal disk 23 located over the roll, suchdisk having an upstanding rim 23b somewhat less in diameter than thedisk itself. Also, the latter has an upstanding spindle 24 passingfreely through an opening in the top II of the cabinet to receive afinger knob 25 secured by a set screw 2511.. About the spindle 24, thecabinet top I I is slightly sunken in its bottom surface with a circularrecess I Ia, this recess and the interior of the rim 23b forming seatsfor the ends of a compression coil spring 25 surrounding the spindle 24.As the assembly appears in Figures 1 and 4, the expansive tendency ofthe spring 26 maintains the disk 23 in locked relation with the roll bythe agency of the pins 23a, so that the roll may be rotated when theknob 25 is manipulated. Should it be necessary, however, to change theroll for one bearing a different formula, it is only necessary to raisethe knob 25 whereby to release the roll from the locking pins 23a, inwhich event the roll may be slightly raised and removed from thecabinet. The action just described is suggested in the illustration ofthe second upper roll from, the right in Figure 1. To facilitate theremoval of the rolls, the front edge of the shelf I3 is concavelyrecessed at I3b under each roll for a better reach to raise and removethe same. The arrangement in reference to the lower set of rolls isprecisely the same as just described, but in inverted relation, thedepth of the apertures I; being ample for the dual function, assuggested in Figure 4.

The frontal columns of the formula rolls are rendered visible from thefront when the cabinet is closed by the provision of slots I5a atcorresponding places in the door I5. Thus, by means of these slots theroll columns of figures or other legends may be brought into View bysimply turning the selected knob 25.

The master cards with which the formula roll columns are intended to beread are grouped in an array upon the door I5. As more clearly shown inthe left hand portion of Figure 3, the card 2'! is a long vertical stripof pasteboard or other firm material and is encased in a retainer plate28 having inturned side and bottom flanges 23a. The card is inserted bybeing slid down into the retainer to the position shown, which leaves asmall portion of the card projecting. above the retainer. Thus, it iseasy to remove the card and replace it by a different one when the datacarried by the retainer is to be changed. One side channel of theretainer receives a wire rod 29 whose upper and lower ends are benthorizontally and sprung into small perforations 29o made in the door I5at points laterally of the slots I511. The rods 29 thus become pintleson which the card bearing retainers 28 are hinged. Various positions inthe hinge action of these are illustrated in the upper portion ofFigure 1. Thus, the retainer is shown flat against the door I5 at theextreme left, fully exposing the slot I5a. The next showing toward theright represents the retainer as partly swung out; the third showingindicates the retainer fully swung out; and the right hand showingindicates the same closed upon the slot I50. While the master card isfully exposed to view in the first position mentioned, only its upperprojected portion is visible when the retainer is closed. Also, therollers are located closer to the front for visibility, by recessing thedoor at I51 when the latter is of thick material, such as wood.

Figure 5 shows a modification of the rolls 20 where it is advisable touse a taller formula sheet. In such event, the cabinet may be laterallyspaced off with partitions 3H and a full-height roll 26d disposed in oneor more of the compartments so formed. As noted, the bearing andmanipulating construction incident to this roll is identical with thatemployed in the previous instance, except that the top I I of thecabinet is used as a bearing and not for manipulating means.

Figures 6 and 6a show a modification of the tension means for holdingthe rolls in place. The spring 26 is now replaced by a forked block 3|which straddles the spindle 2 and serves as a spacer between the disk 23and the cabinet top II. The block is of the proper thickness to beinserted between the spaced parts with a slight amount of friction, sothat it permits the roll to be rotated while holding it in place; andthe outer portion of the block is extended with a lug 3Ia to serve as ahandle.

Figures 7 and 7a show a further modification of the roll retainingmeans. Here it is seen that the disk 23 is dispensed with, and that themedial shelf I3 of the cabinet is replaced by spaced individual shelvesI30 between the cabinet and walls and intermediate partitions 30. Eachupper roll carries a spindle 32 which is reduced with neck portions 32aopposite the shelf I30 and cabinet top II, these parts having slots I311 and Nb, respectively to receive the reduced portions of the spindlewhen the roll is moved in the direction of the arrow in Figure 7a. Theupper portion of the spindle receives a large washer 33 before it entersthe knob 25. This form of control is simple, and the large size of thewasher 33 checks the roll from tendencies to depart from its verticalposition. The same illustration shows a bottom roll and a full-heightroll installed in like manner.

It will be apparent from the above description that a variety offormulas may be compactly housed in the cabinet, yet so easily locatedand controllable as to expose any column in a selected formula to view.Such formulas as require frequent attention will make it necessary tokeep their master card retainers 28 open, in order that the data on theexposed roll column may be readily correlated with that on the mastercard. As to formulas seldom consulted, the corresponding master cardretainers may be kept closed, so

" as to fully conceal affected rolls and divert the attention of theobserver therefrom. In this respect, an illustration may be made. Thus,the master card in Figure 3 shows the ingredients required for thepreparation of a rye bread dough, the title Rye being marked above onthe front and reverse sides of the top projected portion of the mastercard. The chart borne by the corresponding formula roll indicates invertical rows the various quantities of the ingredients required inaccordance with the size of the dough parcel or batch called for. Thus,the dough sponge "age or time since fermented is the first requirementon the master card, and the particular roll is chosen which recites the"age of the sponge on hand. The next consideration is the size of theload or dough unit, and the roll is turned to 2 lbs, 1% lbs., or anydesired size. The figures below now indicate the amounts of basicsponge, rye flour and other ingredients required for the particular unitsize. If the sponge age is greater, a roll of the rye bread serieshaving the corresponding heading is chosen. However, should any type ofdough seldom be required, the closing of the master cards upon theaffected rolls will still expose the name of the variety at the top, tobe conveniently located when wanted. Further, as an additional expedientto distinguish the different formula rolls at sight, I prefer to tintthe various formula sheets or series thereof in different hues orcontrasts, such expedient saving time when the observer has memorizedthe colors of preferred or frequently consulted formual rolls or seriesand can readily recognize or distinguish them. The file drawers l8 areused for the storage of spare formulas, and a small compartment in oneof the drawers may be used for extra master cards as shown.

I claim- 1. A reference system comprising a casing, a set of cylindricalforms rotatably tfisposed therein and tabulated with values in rotarysequence, and a door for the casing immediately in front of the formsand adapted to be opened for the insertion and removal of forms, thedoor having perforations opposite the frontal peripheral portions of theforms to expose a row of said values.

2. The structure of claim 1, said forms being vertically disposed, thedoor being hinged from the side of the cabinet, and the perforations inthe shape of vertical slots.

3. The structure of claim 1, and a master card carried by the dooralongside each perforation and readable with the values exposed throughthe latter.

4. The structure of claim 1, a retainer carried by the door alongsideeach perforation and movable to close the latter, and a master card inthe retainer and readable with the values exposed through theperforation when the retainer is open.

5. The structure of claim 1, a retainer hinged to the door alongsideeach perforation and swingable to close the latter, and a master card inthe retainer and readable with the values exposed through theperforation when the retainer is open.

6. The structure of claim 1, said rolls denoting different subjects, aretainer hinged to the door alongside each perforation and swingable toclose the latter, a master card in the retainer and readable with thevalues exposed through the perforation when the retainer is open, thelatter then forming a cover for the back of the master card, and anextension of the latter beyond said cover and indicating the subject ofthe related roll on the frontal side when the retainer is closed.
